My matches should return following
Customer
Orders
orderNo
OrderAmount
Total

The regular expression i am trying to use return only first match.

C#

static void Main(string[] args)
        {
            //string source = "Test <TEST/>asda 9  <asdas/>";
            string source = "Test <aaa> 2323 </aaa> cvcvc <bbb>asds2323 </bbb>sas";
            //string regExp = @"(<\w+\/>)";
            //string regExp = @"(<.*<\/\w+>)+";
            string regExp = @"(<\w+>\s\w+\s<\/\w+>)+";
            Regex regx = new Regex(regExp);
            MatchCollection collection = Regex.Matches(source, regExp);
            for (int index = 0; index < collection.Count; index++)
            {
                string s = collection[index].Value;
            }
        }

Is it XML right?Why are you not using Linq to read data from the XML?.

This is a light weight library which replaces these codes in one parse. XML will complex the resolution process and requires looping

which is light weight library?Does your xml gonna have long data like more orders or More customer information?

Start by simplifying your regex:

<.+?>

Will catch just the bits you want.
Then, I'd do it like this:

C#

        private void myButton_Click(object sender, EventArgs e)
            {
            string source = @"Dear <customer>
This is to let you know that your following Tickets have been confirmed.
 
<Orders>
<OrderNo> <OrderType> <OrderAmount>
<Orders>
 
Total Amount is <Total>
 
Thanks for doing business with us.
 
Best Regards
Team";
            string regExp = @"<.+?>";
            Regex regx = new Regex(regExp);
            string newData = regx.Replace(source, ReplaceData);

            }

        public string ReplaceData(Match m)
            {
            switch (m.Value)
                {
                default: return m.Value;
                case "<Orders>": return "----ORDERS DETAIL----";
                case "<OrderNo>": return "----ORDER NO----";
                ...
                }
            }

Try it and you'll see what I mean!
